Greatly dissatisfied with Farmers

Farmers has been high in prices and untruthful with their rates. I get a quote for 6 mths, and I set up auto drafts from my account. It has always been a difference of 20-50 dollars more than what I was quoted that was going to be taken out monthly. Every time I call my agent, I'm told it is suppose to even out towards the end of the 6 mths, which never happens. Now after I've tried cancelling the auto drafts, IT WAS STILL taken out of my account. It has been almost a mth, and my request for a refund still has not been taken cared of. I'm sooooo pissed off at them, that I will never come back to Farmers again, and I might write a complaint to the better business bureau.
